PULL-LINE SUPPORT.

Application filed November 19, 1927. Serial No. 234,496.

My invention relates to improvements in supports for pull lines usually employed between the power saw and the oil well operation, which may be at some distance remote from the power. These pull lines are general- 1y constructed of long rod sections, coupled together, and generally supported upon the rollers, whereby the same will have an easy and free reciprocatory movement.

However, a serious disadvantage arises in these pull lines, where the ground surface is unlevel, consequently preventing the proper alinement or" the pull lines for their most satisfactory operation. My present invention aims to compensate for this disadvantage, by providing' a novel pull line support, whereby the supporting pulley may be vertically adjusted for properly setting the pull line in substantial alinement.

The main object of my novel support resides in the fact that the supporting pulley may easily and quickly be adjusted to the proper height from the ground. Another ob ject resides in providing a support which while simple in construction, the same embodies certain constructions which will materially reduce the probability that the same will tilt over when subject to an extraordinary force.

Other very novel objects and advantages will become apparent as my invention is better understood from the specification and claim to follow.

In the drawing Figure 1 represents an end elevation of the support.

Fig. 2 represents a side elevation of the same, and

' Fig. 3 is a horizontal sectional view taken substantially on the line 33 of Fig. 2.

Now for a more specific description of my invention, I refer to the drawings, in which like numerals will designate like parts. My improved support includes a pair of base bars 11, which are of arcuate shape in length, and which are of U-shaped cross section. The intermediate portions of these base bars are connected together, so that their adjacent end portions are adjacent and diverged outwardly from each other. A pair of upstanding posts 2-2 also of substantially U-shape in cross section, have their lower end portions spanning the longitudinal edges of the respective base bars, while suitable bolts 3 connect the respective upstanding posts to the base bars, in a manner clearly shown in Fig. 3.

The respective posts are formed with longitudinally spaced openings, the openings in one ot the post members being in horizontal registry with the corresponding opening of the opposed posts. A spacing block 5 is interposed between the upper end of the post, while a bolt 6 passes through the end of the post, and the block, for securing said upper post ends in spaced relation to each other.

A guy rod 7 has each end portion thereof threaded. The upper end of the rod is adapted to pass through the flange at one edge of the post, and a nut 8 secures the same thereto. The lower end of the rod projects through the top flange of the adj acent base bar end, while a nut 9 secures the same thereto. A second guy rod 10 is connected at its upper end to the opposite edge of the opposed post, while the lower end of the rod connects in like manner, the opposed base bar at its opposite end.

The pulley wheel 11 is adapted to be mounted between the respective posts by having a bolt 12 bridging registering openings in the respective posts, and upon which the pulley wheel is rotatably mounted. A nut 13 is threaded upon one end of the bolt 12, and is removable for allowing the pulley to be adjusted upwardly or downwardly between the post. a

It will thus be seen that I have provided a novel support for maintaining the pull line employed in oil well operation, in proper disposition to allow the rod free movement, without the possibility of the same buckling or bending in any manner. It is to be understood that no limitations are to be placed upon the type of the post, nor the length of the base bars, as the same can be varied in dimension without any degree departing from the spirit of this invention, or the scope of the appending claim.

Having thus described my invention, what I claim as new is In a pull line support, a base consisting of a pair of arouate shaped bars secured together at their central portions, a pair of upstanding spaced posts secured at their lower ends to opposed outer sides of the arcuate base bars and at the intermediate portions thereof, the pull line supporting Wheel mounted for rotation between said posts, a bolt for adjusted
